6 Claims.

This invention relates to flush tanks, and more particularly to a water guard, the primary object of the invention being to provide means which may be readily and easily positioned within a flush tank adjacent to the ball valve thereof, whereby the lateral pressure directed to the ball valve caused by the water passing the ball valve and entering the outlet or discharge fitting of the tank, will be equalized, to insure a true and perfect seating of the valve at all times.

Another object of the invention is to provide means used in conjunction with the ball valve rotor forming a part of my application filed April 27, 1938, whereby the water will be directed against the blades of the rotor or guide, insuring the proper rotation of the ball valve as it is moving to its seat.

A still further object of the invention is to provide means for compensating for the variation of water pressure in the system, of which the flush tank forms a part, to prevent wobbling of the usual ball valve, as it is moving to its seat.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a transverse sectional view through a flush tank equipped with a water guard, constructed in accordance with the invention, the Water guard being shown in plan.

Figure 2 is a side elevational View of the guard.

Figure 3 is a vertical sectional view through the guard, and taken on line 3--3 of Figure 1.

Figure 4 is a transverse sectional view through the guard.

Figure 5 is a side elevational view of the guard.

Figure 6 is a front elevational view illustrating the guard.

Figure 7 is a rear elevational view of the guard. Referring to the drawings in detail, the guard comprises a substantially cylindrical body portion indicated generally by the reference charac-' ter 5, the body portion being provided with an offset portion of a shape and construction to fit over the usual overflow pipe 6 of a flush tank structure.

The reference character 1 designates the ball valve of the flush tank, and as shown is seated in the. discharge fitting of the flush tank, cutfleeting member'9. As clearly shown by Figure 4 of the drawings, this bafile or deflecting member 9 is disposed at an oblique angle with respect to the vertical, the free end thereof lying in spaced relation with the wall of the flush tank with which it is used.

Owing to the construction of the deflecting member 9, it will be obvious that the member 9 may be adjusted to vary the space between the free end thereof and adjacent wall of the flush tank, to regulate the fiow of water past the free end of the deflecting member 9.

At the opposite side of the body portion 5, is a cut-out portion or opening Hi, the opening being formed by stamping out a portion of the body 5, the portion stamped from the body ibeing extended laterally and rearwardly, as indicated at l I, where it contacts. with the inner surface of the flush tank, securing the body portion against movement, and at the same time preventing water from passing between the body portion 5 and adjacent wall of the flush tank, at a point adjacent to the ball valve 1. This member ll may also be adjusted to insure a close fit against the wall of the flush tank.

The reference character l2 designates a brace free end thereof being curved to fit against the inner surface of the flush tank, and cooperates with the member I l in securing the body portion in an upright position at all times.

From the foregoing it will be seen that due to the construction shown and described, when the valve 1 is operated or moved upwardly from its seat toallow the water in the tank to pass through the discharge fitting, which in the present showing is indicated by the reference character l3, the water passing into the tank will follow the paths as indicated by arrows in Figure 1 of the drawings, with the result that the water will strike the blades of the valve guide at the desired angle to rotate the ball valve and cause the valve to seat properly.

It will further be seen that due to this construction, pressure at both sides of the ball valve will be equalized, eliminating any wobbling of the ball valve as it is moving towards its seat, regardless of the water pressure in the pipe line feeding the flush tank.

While I have shown and described a water guard for flush tank valves, so constructed that it may be readily positioned over the usual overflow pipe of a flush tank system, it is to be understood that the construction of the water guard may be varied, and may be secured to the overflow pipe by means of suitable bolts and nuts, without departing from the spirit of the invention.

I claim:

1. The combination with the ball valve of a flush tank, of a water guard for the valve, comprising a cylindrical body portion positioned within the tank and housing the ball valve, said body portion having openings formed in the wall thereof and disposed directly opposite to each other, and means adjacent to the opening for directing water into the body portion in opposite directions, causing a swirling motion of the water and valve.

2. The combination with the ball valve of a flush tank, of a water guard for the ball valve, comprising a cylindrical body portion fitted within the tank, and housing the ballvalve, means for supporting the body portion in an upright position and in spaced relation with the bottom of the tank, said body portion having openings in the side thereof, and battles arranged adjacent to the openings for directing water into the housing at opposite sides of the housing, and in opposite I directions to cause a swirling motion of the water and ball valve.

3. The combination with the ball valve of a flush tank, of a water guard for the ball valve, comprising a cylindrical body portion positioned within the tank, and housing the ball valve, said body portion having openings in the side thereof the lower edges of the openings being disposed below the discharge fitting of the flush tank, the up er edges of the openings being disposed above the upper end of the ball valve when the ball valve is seated, and baffles arranged adjacent to the openings and adapted to direct water into the body portion in opposite directions, at opposite sides of the body portion, setting up a swirling motion of the water and ball valve.

4. A water guard for the ball valves of flush tanks, comprising a substantially cylindrical body portion fitted within the tank and housing the ball valve with which it is used, said body portion having openings disposed in opposite sides thereof, 'bafiles formed on the body portion adjacent to the openings and adapted to direct water into the body portion at an oblique angle with respect to the vertical, whereby a swirling motion of the water and valve is assured.

5. A water guard for the ball valves of flush tanks, comprising a substantially cylindrical body portion having an offset portion adapted to be fitted around the over flow pipe of a flush tank securing the body portion in position, said body portion adapted to completely house the ball valve, the wall of the body portion being spaced from the ball valve, said body portion having lateral openings establishing communication between the i'lush tank and the interior of the housing, and baffles formed adjacent to the openings for directing water into the body portion in opposite directions at opposite sides of the body portion, causing a swirling motion of the water and ball valve.

6. A water guard for the ball valves of flush tanks, comprising a substantially cylindrical body portion adapted to be fitted within the flush tank and completely housing the ball valve, means for supporting the body portion in spaced relation with the ball valve providing a water pas sageway between the body portion and ball valve, said body portion having substantially wide openings formed in the side thereof, establishing communication between the tank and body portion, and baiiles adjacent to the openings for directing water into the body portion in opposite directions, causing a swirling motion of the water Within the body portion to rotate the ball valve.
